o RADIATOR.,

T0v all whom z'fmay concern:

Be it lmown that I, CHARLES S. MooNEY,

a citizen o f the UnitedStates of America, residing at Detroit, in the countyv of Wayne andvState of Michigan, have invented cer# tain new and useful Improvements in -Ra-V diators, of which the following is a specification, reference being had thereln vto the accompanying drawings. o

In the construction and operation of radlators -for automobiles it is desirable that they present a radiating surface that is large in proportion to the water columns and contain a minimum of joints whereby their eiiiciency is enhanced and their liability to leakage diminished.Y It is desirable also that the parts be so disposed as to afford a cer` tain iiexibility "and vibrations.

to avoid injury from jars This invention relates to radiators whereiny a very large air radiating surface in proportion to the water columns is combined with a simplicity of construction that inimmizes the joints and number of parts and provides for a greater efiiciency because of the manner in which the air passages battle the air current, while the construction is suinciently flexible` or'yielding to resist injury from the shocks and vibrations incldent to unfavorable service conditions.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended c1a1ms:

In the drawings,

specification ef Letters Patent. Patented May 14,. 1915, Application sied-september 5, 1916. seriei ne. 118,370.

Referring to the drawings, afraine 1 of standard type has theusualupper header 2 pand lower header 3, in which a panel of water column elements, or the ,so called grille or honeycomb is pla ced.

This honeycomb consists of a series' if upright water sections mountedv vbetween the lower wall 4 of the upper header, and the upper wall 5 of the vlower header in spaced relation to provide the requisite air circulahaving impressed Vthereon'a tortuous Channel with substantially horizontal loops 7 extending frommargin to margin and terminatingA at the upper end portion in an uption. f Each element has a sheetmetal side 6v I' right arm `8 and at the lower endportion in a corresponding downturned arm 9. Al

companion side 10 that is reversely impressed, is secured against the part 6 in such manner that the embossed portions or impressions are in register while the margins outside of the impressed` portions are intimately united by any suitable form of non-leakable joint. This may be effected by appropriate spot-welding, by brazing,

soldering or in any other preferred manner. The members are of a width in proper proportion to the walls 4 and of the headers. The channels or Vpassages formed by the impressions are in communication with the interiors of the headers through any preferred connections. Nipples 11 inserted in the arms 8 and 9, and headed down in openings in the walls through which they are passed, afford one such form of union. ,j

The elements may each be formed of the separate sides 6 and 10,- or a single blank 12 may be provided with reverse impressions 13, and may be folded on its axis of symmetry 14, with suitable hermetical joinder of the contacting faces.

In Fig. 8, provision is shown for an element that has not'only the lateral elastici-ty aiiorded by the arrangement of parts just described, but also longitudinal extensibility A blank 15 with impression 16 is slotted vas at 17 between the loops. The element formed o1' such sides is longitudinallyelastic, and accommodates itself to slight variationsin the frame while being mounted therein and also successfullv resists vibrations andshoeks without leak.'-

age. f 11e the impressions herein shown provide an eiiiclent channel, difl'erentrequirements of service and conditions of use are of course met by suitable proportion and design of such passages, the form herein illustrated being merely one of a number which. are eHicacious in suitably circulating the Water in Contact With large surfaces cooled by contact with the atmosphere. One of the plates may be plain as shown in Fig. 9.

As a result of this construction, a radiator is obtained that presents a very large aircooled surface in proportion to the water channels and effectively baffles the air currents to increase and lengthen the period of contact with the radiating Walls. The portions of the plates around the impressions .preclude the necessity of other fins, and

therefore simplify the structure Without impairment of the eificiency of the radiator.

The elements are elastic and slightly yield-` able, and this feature, together With the small number of necessary joints, minimizes any leakage under even severe service.

Obviously, changes in the details of construction may be made Without departing from the spirit of the invention, and I do sage through the element, the margins of the sides being slotted to permit limited longitudinal extension of the element.

2. In a radiator, an upper header, a lower header and a series of Water column elements i connecting the headers, each consisting of a pair of sheet metal sides oppositely impressed to form a tortuous, continuous and uninterrupted Water channel from end to end thereof, the exterior conformation of theV sides forming air-baffling projections and radiating fins having slots afording lateral` and longitudinal elasticity to the element.

In testimony whereof I aiX my signature in the presence of tWo Witnesses.
